'Trojan horse' proteins used to target hard-to-reach cancers: Scientists at Brunel University London have found a way of targeting hard-to-reach cancers and degenerative diseases using nanoparticles, but without causing the damaging side effects the treat

Scientists at Brunel University London have found a way of targeting hard-to-reach cancers and degenerative diseases using nanoparticles, but without causing the damaging side effects the treatment normally brings.

In a huge step forward in the use of nanomedicine, the research helped discover proteins in the blood that disguise nanoparticles so they are absorbed into cells without causing inflammation and destroying healthy cells.

New Technique Could Harvest More of the Sun's Energy

As solar panels become less expensive and capable of generating more power, solar energy is becoming a more commercially viable alternative source of electricity. However, the photovoltaic cells now used to turn sunlight into electricity can only absorb and use a small fraction of that light, and that means a significant amount of solar energy goes untapped.

Unusual Electronic State Found in New Class of Unconventional Superconductors: Finding gives scientists a new group of materials to explore to unlock secrets of some materials' ability to carry current with no energy loss

A team of scientists from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, Columbia Engineering, Columbia Physics and Kyoto University has discovered an unusual form of electronic order in a new family of unconventional superconductors. The finding, described in the journal Nature Communications, establishes an unexpected connection between this new group of titanium-oxypnictide superconductors and the more familiar cuprates and iron-pnictides, providing scientists with a whole new family of materials from which they can gain deeper insights into the mysteries of high-temperature superconductivity.

Top: Ripples extending down the chain of atoms breaks translational symmetry (like a checkerboard with black and white squares), which would cause extra spots in the diffraction pattern (shown as red dots in the underlying diffraction pattern). Bottom: Stretching along one direction breaks rotational symmetry but not translational symmetry (like a checkerboard with identical squares but stretched in one of the directions), causing no additional diffraction spots. The experiments proved these new superconductors have the second type of electron density distribution, called a nematic.

Light propagation in solar cells made visible

How can light which has been captured in a solar cell be examined in experiments? Jülich scientists have succeeded in looking directly at light propagation within a solar cell by using a trick. The photovoltaics researchers are working on periodic nanostructures that efficiently capture a portion of sunlight which is normally only poorly absorbed.

Through use of a glass fibre tip, the researchers were able to measure the amount of light that had actually been captured in the solar cell using a method called near-field optical microscopy.

Endomagnetics receives IDE approval to initiate US trials

Cancer healthcare company Endomagnetics announced today that it has received Investigational Device Exemption (IDE) approval from the United States Food and Drug Administration (FDA) to initiate a pivotal clinical trial to evaluate the safety and effectiveness of the SentiMag® and Sienna+® magnetic sentinel lymph node biopsy system in the management of breast cancer.

The SentiMag® and Sienna+® system gives surgeons the ability to locate the sentinel lymph nodes draining a tumour accurately and reliably as part of cancer staging - the process of determining whether cancer has spread.
